If absolutely must wash them, do it in the kitchen sink
(remove the dirty dishes first), or in the bathroom sink
(rinse the sink after hubby shaves). Swish them around
in soapy water gently, let soak for 10-15 minutes, then
rinse til all the soap is out. Don't ever wash them in
the washing machine (at least not til you're done quilting).
Use color guard if desired. (I've never had one bleed).
squeeze water out and iron them instead of putting in the
dryer.
